Question

The work-energy theorem states that a force acting on a particle as it moves over a ______ changes the ______ energy of the particle if the force has a component parallel to the motion.

Choose the best answer to fill in the blanks above:

distance / potential
distance / kinetic
vertical displacement / potential
none of the above

Answer 1

distance/ kinetic

Step-by-step explanation:

According to the work energy theorem, the work done by all forces is equal to the change in kinetic energy of the body.

So, As the force is applied in the same direction of the distance traveled,so only the kinetic energy of the body changes as after application of force, the speed of the body changes.
